Model-wise, it's like 95%, but that's not the whole story.
It's hard to give a percentage for the entire vehicle, because the most complicated parts need to be done now. Like, I need to get in contact with Barnabas and learn how to animate the lights properly (so that the emergency lights are an animation within the model (I need to learn how to get each light to appear/disappear in a single frame), not a bunch of scripting that doubles as a lag meter) without breaking the steering animation.
Add class projects and finals, and the immediate future doesn't look good, but I'm hoping (not guaranteeing) to release the ambulance before January 1.
